Tekkebak Tunnel

Tekkebak Tunnel (Tekkebak Tüneli), is a highway tunnel constructed in Ordu Province, northern Turkey.

Tekkebak Tunnel is part of the Samsun-Ordu Highway  within the Black Sea Coastal Highway, of which construction was carried out by the Turkish Nurol-Tekfen-Yüksel joint venture. The 170 and 135 m-long twin-tube tunnel carrying two lanes of traffic in each direction is flanked by 261 - 257 m-long Kozbükü Tunnel in the west and 3805 - 3825 m-long Ordu Nefise Akçelik Tunnel (named in honour of the late female engineer Nefise Akçelik) in the east on the same highway.

The tunnel was opened to traffic on 7 April 2007 by Turkish Prime Minister Recep Tayyip Erdoğan. Dangerous goods carriers are not permitted to use the tunnel.
